Constitutional Classifiers++: Production-Grade Defenses against Universal Jailbreaks

ICLR 2026poster

We introduce enhanced Constitutional Classifiers that deliver production-grade jailbreak robustness with dramatically reduced computational costs and refusal rates compared to previous-generation defenses. We first identify vulnerabilities in existing systems that evaluate model outputs without rega…

CARMS: Categorical-Antithetic-REINFORCE Multi-Sample Gradient Estimator

NeurIPS 2021poster

Accurately backpropagating the gradient through categorical variables is a challenging task that arises in various domains, such as training discrete latent variable models. To this end, we propose CARMS, an unbiased estimator for categorical random variables based on multiple mutually negatively co…
